Abstract (en)
[origin: US4404324A] The invention relates to a curable adhesive based on a reactive acrylate and/or methacrylate copolymer. The reaction principle, on which the curing of the adhesive is based, is the reaction of the hydroxyl groups of the omega -hydroxyalkyl esters of acrylic and/or methacrylic acids with the isocyanate groups of the polyisocyanates or their partial reaction products with polyols. The inventive adhesives can be used without solvents or with only a slight content of organic solvents. They adhere well to plastic and metal surfaces, even when exposed to the effects of water or water vapor. The best values for the drum peel strength are obtained from acrylic copolymers whose molecular weight falls in the range of 1,000 to 3,000.
